Visceral adiposity is associated with metabolic disorders, but little is known on the underlying pathophysiological mechanism. One possible link might be the release of various signalling and mediator proteins, named adipokines. Our hypothesis was that dependent on genetic background factors are released which might trigger a primary disease susceptibility. This study characterizes the adipokines released from visceral adipose tissue from two metabolic healthy mouse strains, i.e. C57BL/Ks (BKS) and C57BL/6 (C57), of which the former genetic background is more sensitive to develop diabetes following metabolic challenge. Using liquid chromatography (LC)-electrospray ionization (ESI)-MS/MS, a reference map comprising 597 adipokines was generated (http://www.diabesityprot.org). Thirty-five adipokines, including six not previously described ones, were differentially released between the mouse strains. Most notable is the reduced release of the adiponectin-binding protein T-Cadherin (CAD13) in BKS mice. This observation highlights the importance of secretome profiling in unravelling the complex interplay between genetic diversity and lifestyle.
